Application filed March 23, 1915. 5 Serial No. 16,458.

To all whomz't may concern:

Be it known that I, CLAES Bronx, a citizen of the United States, residing at the city of' Cranston, in the county of Providence and State of Rhode Island, and whose post-office address is 106 Massasoit avenue, in said city, have invented certain new and useful Improvements in \VireJVinding Devices, of which the following is a specification. 7

My invention relates to an improved device adapted for use in winding wire to form electric coils, and for filling supply bobbins.

The invention consists of a swinging frame carrying an idler wheel and a delivery wheel, both said wheels designed to traverse together in delivering the wire around a revolving spindle, slidable stoppieces to limit the traverse movement of said wheels, means to respectively permit the wire to feed in straight layers, lengthwise of the spindle, each layer having an equal number of turns, to form a coil having flat sides, and to feed in such manner that the turns of one layer come between the turns of the next contiguous layer, to form a coil having tapering sides, and means to regulate the distance of traverse movement of said wheels.

In the accompanying two sheets of drawings, wherein like reference characters inclicate like parts, Figure l is a front elevation of my improved wire-winding device. Fig. 2 is an end view of the same. Fig. 3 is a plan sectional view of the device, showing the relative position of parts, as at the completion of one style of electric coil. Fig. & is a rear view of the device, showing a screwshaft for regulating the traverse movement of the wire guide wheel and the delivery wheel. Fig. 5 is an enlarged section taken on line m.a2. of Fig. 3, showing how the wire layers are built up to form a coil. Fig. 6 is a front view of the wire guide wheel and the delivery wheel, partly in section and illustrating how both said wheels are caused to traverse together in the feeding movement of the wire. Fig. '7 is a cross section of the device, taken on line y .g of Fig. 3, showing the course the wire takes by the revolving spindle. Fig. 8 is a sectional view taken on line e0.w. of Fig. 1, showing means to table,

zontal-shaft b fiXed 'at the lower connection .with a permit the deviceto operate in feeding the wire to form a coil of the style illustrated in.

F ig. 10. Fig. 9 shows a latch member for holding the rack barfree of engagement with a pinion fast on the screw-shaft. Fig. 10 shows a coil formed with a succession of shorter layers, offset from each other, .to form a coil having tapering sides. Fig. 11 1s a rear view of the device, showing a scale plate to reveal the distance of traverse'movement of the wire, and, Fig. 12 is a cross-section taken on line 2.-.2. of Fig. 11.

. In carrying out my invention I employ a standard -a. which is secured upon a by means of bolts -a A vertical frame -Z1 is pivotally mounted on a horipart of the standard, and said frame carries at its upper part horizontally-arranged rods,

2 and screw-shaft b*. The rods b Z2 are fiXecl to the frame, and on the former rod is a slidable wire guide wheel -c, which has flat projecting flanges c designed to have a sliding fit upon the side faces of a wire delivery wheel (Z slidable on the'rod b The web (Z of the wheel (Z is of a thickness equal in the diametrical size of wire for feeding to form the coil. Each wheel -0 and d is peripherally grooved to receivethe wire eand provided with rollers 0 (see Fig. 3.) to lessen the friction in the lateral movement of said wheels. On the standard a is a horizontal spindle f which is driven by power through a belt pulley f fast on said are fixed on the spindle, to serve as head.

pieces -f in building up this style of coil, to have opposed straight sides, as shown in said figures.

The snaft -b has right and left hand screw-threaded portions in engagement with the nut ends g of stop pieces g-, which are perforated to loosely receive the rods b and said shaft is pro-- vided with a knurled head to grasp upon in positioning said pieces gthe proper distance apart for the traverse movenient of the feed wire. I

In starting to build up a coil, as in Fig. 5, aftc the first traverse movement of the wire has been made by the spindle, to form the inner layer, as at a point -ethe head piece f causes the feed wire to move outwardly and directly upon the last turn made in said layer, thus the frame 7) is made to swing back in the direction indicated by the arrow shown in Fig. 2, this slight rearward movement being equal to the thickness of thefeed wire, to make the next return traverse layer.

On the standard -a is secured a rod -h which has pull-spring connections -2' with the frame -Z), for holding the wheel dclose to the spindle.

Having the guide wheel c arranged to embrace the delivery wheel (Z, in the manner shown in Fig. 6, permits the wire to feed in alinement with the peripheral centers of both said wheels, and thereby the wire is enabled to form its succession of layers evenly throughout the feeding operation to form the coil. v

In Figs. 8 and 9 I show a means whereby my improved device is adapted to operate the wire in feeding to build up a coil to have opposed tapered sides, as in Fig. 10.

Pivoted on the standard ais a rearwardly extending rack bar jfor engagmg a pinion 7a, fast on the screw-shaft b. A spring -Z is secured on the standard and has its free portion in yielding contact with the rack bar j, for holding the latter in mesh with the pinion 7c. A flat leaf spring member -m is vertically secured on the standard -a, and said member, which forms a finger latch, has a lug m to bear upon the top of the rack bar -j, for holding the latter out of engagement with the pinion, during the time the device operates to form the style of coil shown in Fig. 5.

To operate in forming the style of coil shown in Fig. 10, the latch mis pressed upon to allow the spring -Z to force the rack bar jinto engagement with the pinion.

On the spindle is secured a tubular member n for the wire to feed upon, and said member has its ends upturned, as at -n in order that the first formed wire layer -e may be held evenly throughout its course around the said member n. At the moment this first or inner layer c is formed a slight rotation pered sides, in the manner shownin Fig. 10.

Short expanding coil springs encircle the rod -Z) to form buflers, as at +p, to assist the wheels 0-, din the initial movement of the wire in feeding to form each layer.

To determine the exact distance of traverse movement to form the inner layer e-, in building up of a coil, a plate --ris secured acrossthe back of the frame Z) and provided with graduation marks, as at --r, and by turning the screw-shaft a pointer, which is carried by one of the stop pieces, as at s, is brought to the index mark of the scaleand the measured distance had for thedevice to operate in forming the desired width of coil.

What I claim and desire to secure by Letters Patent, is,

1. In a device of the character described, a standard, a revolving spindle mounted on the latter, means secured on the spindle to limit the length of traverse to form the inner wire layer, a pivotal frame carrying a guide wheel and a delivery wheel, both said wheels constructed to traverse laterally together in feeding the wire about the spindle, a. shaft mounted on the frame and having right and left hand screw-threaded portions, stop pieces having nut ends engaging the threaded portions of said shaft, yielding means to hold the frame toward the spindle, a pinion carried by the said shaft, a rack bar pivoted on the standard, means to hold said bar in engagement with the pinion during the operation of forming a coil with tapered sides, and. means ,to prevent rotation of the screw-shaft during operation to form a coil with straight sides.

2. In a device of the character described, a power-driven spindle, a tubular member fixed upon the latter and having upturned ends. to receive the winding feed wire in the form of a straight layer therebetween, a pivotal frame carrying a wire delivery wheel and a wire guide wheel embracing the latter, to permit the wire to feed in direct.
